#6 Use Only 40MHz-wide Channels with Strong Signals

As mentioned, in order to pass the 130Mbps ceiling on wireless N connections, you must double the channel-width from 20 to 40MHz.

However, you might reconsider enabling channel bonding if all the users don't have a good signal.

This is because it might actually have a negative impact on clients with low signals, and you're better off leaving it alone.
